MACHINE FOR BAGGING AND WEIGHING GRAIN.

SPECIFICATION forming part of Letters Patent No. 786,475, dated April 4, 1905.

Application filed July 25,1904. Serial No. 218,137.

To (all whmn it 777/017] concern:

Be it known that I, JAMES BERNARD VVIL- LIAMS, a citizen of the United States, residing at Minden, in the parish of Webster and State of Louisiana, have invented a new and useful Machine for Bagging and WVeighing Grain, of which the following is a specification.

This invention relates to certain improvements in machines for weighing and bagging grain of that general class shown and described in Letters Patent granted to me on the 18th day of August, 1903, under No. 736,663.

The object of the invention is to improve the construction and operation of the machine by providing an auxiliary valve for directing the flow of grain or other material from the hopper into the discharge-chutes without affecting the main valve.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes in form, proportion, and minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

In the accompanyingdrawings, forming part of this specification, Figure 1 is a side elevation of the machine. Fig. 2 is an end view. Fig. 8 is an enlarged detail view, partly in section, of the main and auxiliary valves.

Similar numerals of reference indicate cor responding parts in all the figures of the dra\ ings.

The frame of the machine, which may be formed. of metal or other suitable material, is preferably forged or east, as shown, and con- .sists of the supporting-legs 5 and longitudiported the divergent chutes 11 and 12, said chutes leading from a hopper 13, as shown.

Disposed within the hopper 13 at the juncture of the chutes 11 and 12 is a main valve 14, which regulates the flow of grain and dis charges the same alternately through said chutes. The valve 14 is secured in any suitable manner to a rock-shaft 15, journaled in bearings formed in the flanges 10, said rockshaft being provided with terminal crankarms 16 and 17, arranged at right angles to each other, as 'shown, and connected, respectively, by means of pitman-rods 18 and 19 to the inner ends of the scale-beams 20.

The scale-beams 20 extend longitudinally of the frame and are provided with terminal brackets 21, the latter being fulcrumed in the side bars 6 and 7 as indicated at 22. Pivoted on the brackets 21 are substantially rectangular bag-supporting bails or frames 23, and depending from said frames are threaded rods or hangers 241;, to the ends of which are secured adjustable platforms 25. The mouth of the bag is supported in distended position on the bail or frame by rods 26, provided with intermediate bag-engaging spurs or teeth 24, said rods being journaled in the bails and provided with terminal cranks 27, by means of which said rods may be rotated so as to cause the spurs to project downwardly and release the bag after the latter has been filled.

The relative position of the crank-arms 16 and 17 with respect to the pitman-rods is such that when either of the scale-beams is overbalanced the upward movement of the connecting-rod will bring said rod in direct alinement with its respective crank-arm, or, in other words, on dead-center, as clearly shown in dotted lines in Fig. 1 of the drawings, thereby locking said valve and preventing any further movement of the same until the opposite bag or sack has been filled.

As a means for preventing the flow of grain or other material from coming in contact with the main valve or falling on the latter when the scale-beams begin to tilt an auxiliary valve 28 is provided, said valve being pivoted within the hopper 13 above the main valve, as

clearly shown in Figs. 1 and 2 of the drawings. The auxiliary valve 28 is provided with crank-arms 29, to which are pivoted depending rods or hangers 30, the hooked ends 31 of which extend in the path of movement of the crank-arms 16 and 17, so that when either scale-beam is tilted or over-balanced the crank-arms of the main valve will engage the hooked ends of the depending rods or hangers and automatically shift the auxiliary valve, thereby protecting the main valve and preventing any inaccuracies caused by the weight of the grain which would otherwise fall on said valve.

Pivoted withinthe chutes 11 and 12 are cutoff valves 32 for preventing the column of grain within said chutes from flowing into the sack after the scale-beams are overbalanced, said cut-off valves being movable to open and closed positions through the medium of rods 33, one end of each of which is connected to the scale-beam and the opposite end thereof to the cut-off valve, as shown.

In operation the grainis fed fromathresher or other source of supply into the hopper, and, assuming the main and auxiliary valves to be in the positions shown in Fig. 1 of the drawings, the grain will flow through the chute 12 into the bag or sack until a predetermined quantity has been delivered thereto, when the scale-beam will tilt. As the scalebeam tilts the initial upward movement of the connecting-rod will shift the main valve to the central position, while a further movement of said rod will cause the crank-arm 16 to engage the hooked end of the adjacent hanger and simultaneously move both the main and auxiliary valves to closed positions, thereby cutting off the supply of grain to the chute 12 and directing it through the chute 11 into the opposite bag or sack. The movement of the scale-beam also serves to auto matically close the cut-off valve 32, thereby preventing the column of grain within the chute 11 from flowing into the sack after the main valve is closed.

Having thus described the invention, what is claimed is- 1. In an automatic weighing and bagging machine, a hopper, discharge-chutes leading therefrom, a main valve, scale-beams connected to said valve, and an auxiliary valve arranged in advance of the main valve and operable thereby.
